Cruise

From [nici](http://huamulan03.blogspot.com/2010/10/xxxholic-10-eternal-sabbath-1-by-souryo.html): Cruise is the story of Yamada Kohei, a doctor who gives up a landlubber medical career to serve as a ship's physician, and the people he meets on board Japan's largest luxury liner, the Phoenix. He rejects a university colleague's insistence that he turn to teaching instead, preferring to stay and learn about life as it happens from the ship's passengers.
